Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, covering the safety profile. The description adds only the source URL and return type, with no details about data contents, columns, or expectations. This goes slightly beyond annotations but lacks substantive behavioral context.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is short and has no padding, but it is mostly a hierarchical title followed by a URL and return type. It is not front-loaded with an action or purpose, and the repetitive title could be considered waste. It earns a middle score for brevity without efficiency.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema and no parameters, the description is the only source of context. It fails to explain what specific convertible bond data is returned, such as columns, time range, or whether it is a snapshot. Given the abundance of sibling bond tools, this is insufficient for an agent to confidently select this tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has zero parameters, so the baseline for parameter semantics is 4. The description provides no parameter-specific details, which is appropriate since none exist. No further compensation is needed.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description is essentially a title: 'Eastmoney Data Center - New Stock Data - Convertible Bond Data'. It states the resource and source but lacks a specific verb like 'get' or 'list'. The return type indicates it returns convertible bond data, but this doesn't clearly distinguish it from numerous sibling convertible bond tools such as bond_zh_cov_info or bond_cov_comparison.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no guidance on when to use this tool versus alternative bond tools. No mention of use cases, exclusions, or alternatives. The description simply names the data source and return type, leaving the agent to guess when this is appropriate.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
